[Leet Code - eazy] 1108. Defanging an IP Address

Given a valid (IPv4) IP address, return a defanged version of that IP address.

A defanged IP address replaces every period "." with "[.]".

 

Example 1:

Input: address = "1.1.1.1"
Output: "1[.]1[.]1[.]1"

Example 2:

Input: address = "255.100.50.0"
Output: "255[.]100[.]50[.]0"

/**
 * @param {string} address
 * @return {string}
 */
var defangIPaddr = function(address) {
    return address.split('.').join('[.]')   
};
